In the beginning of the episode, SpongeBob has a dream where he has to save someone from being tied up on railroad tracks until he sees a fish named Jack M. Crazyfish and they played rock, paper, scissors. SpongeBob won, but Jack M. Crazyfish cheats and they argue. It was a nightmare and SpongeBob loses the battle. His dreams disturb Gary's sleep all night. When SpongeBob goes to his bathroom to brush his teeth, he cannot open his toothpaste, so he uses a wrench to open it. But he accidentally gets the wrench stuck in his eyelid and gets a hideous black eye from the accident.
Whenever people notice SpongeBob's black eye, he tells them that he was fighting Jack M. Crazyfish, and he got the black eye from doing that. Later, when Jack M. Crazyfish arrives at the Krusty Krab and says he is looking for SpongeBob, the customers tell Crazyfish the story SpongeBob said. SpongeBob is very afraid and wants to tell him the truth, so he goes back home and gets the wrench and the toothpaste.
SpongeBob demonstrates it to Jack M. Crazyfish what really happened to him. SpongeBob then got a second black eye. Jack M. Crazyfish tells him that he just came to the Krusty Krab because he has heard that SpongeBob makes great Krabby Patties, and he is hungry for one.
SpongeBob then serves him Krabby Patties, but because he has two black eyes, he cannot see very well. The patties then go flying to Jack M. Crazyfish. Jack M. Crazyfish loses his temper and gets mad and challenges SpongeBob to a game of rock, paper, and scissors. SpongeBob wins the first time, but he did not know that Jack M. Crazyfish had cheated on him, and SpongeBob yells "NO!" As the episode ends.

- When SpongeBob throws some things on Gary, he throws the shirt with the inscription "I'm with stupid," which is a reference to the episode of the same name.
- SpongeBob tells Patrick that Jack M. Crazyfish is about 60 feet tall. 60 feet would be about 4-6 stories high, or the length of a bowling lane.
- Manatees, also known as sea cows, make their only appearance in this episode.
- Technically, in a way, there is such a thing as a pain gland called nerves.
- SpongeBob tells Sandy he got the black eye in a fight with Jack M. Crazyfish. However, when he tells the story, he says that he got the black eye by "miscalculating the trajectory of the cup, and the straw jabbing him in the eye," and that does not involve Jack M. Crazyfish.
- Frank says to SpongeBob that sponges do not have eardrums, but in "The Inside Job," SpongeBob has an eardrum.

- SpongeBob's alarm clock goes off at a lower pitch in this episode.
- When SpongeBob is talking to Gary and says, "No, no, Tuesday night was the one with the 30-foot librarian," one of his white teeth turn yellow for a split-second.
- In SpongeBob's bathroom, when he turns muscular and tries to open the toothpaste, the bubbles by his hand stop moving for a moment.
- The music when SpongeBob tries to open the toothpaste is not the usual Hawaiian guitar, but has a harpsichord, and a bassoon.
- When SpongeBob looks at himself through the mirror after getting hit in the eye with the toothpaste cap, the wrench is in his left hand. But when he slips on the cap and hits one of his eyes with the wrench, it's in his right hand.
- When SpongeBob says, "Oh I mean I..." and Patrick says, "I know what you mean," there appears to be a few frames of animation cut with Patrick's expression suddenly changing, which implies there may have been a deleted scene animated, but was removed in the final cut.

- When SpongeBob says, "Hi Sandy," part of his white shirt is black.
- In the scene where Jack M. Crazyfish throws a tire at SpongeBob, they are on a sidewalk. Shortly after when Jack M. Crazyfish runs away crying, the sidewalk disappears.
- When SpongeBob tells his story to Sandy, in the prologue, SpongeBob does not have a hat on. However, when Jack M. Crazyfish ran all the way home leaving behind a pool of tears, SpongeBob is wearing his Krusty Krab employee hat, but there is no anchor on that hat. When SpongeBob drinks the tears, he does not have a hat on again.
- When a close-up of the clam sign is shown, the Krusty Krab sign is misspelled as "Krysty Krab." Also, the y is backwards.
- The Krusty Krab sign also looks darker than usual.
- When Frankie Billy first appears and Mr. Krabs comments about how late SpongeBob is, he is in his normal color scheme, but when SpongeBob walks past him and Evelyn Annette, Frankie Billy has a different color scheme similar to Ivy.
- During the telling of his story in the Krusty Krab, SpongeBob says, "I emerged from my fruit-shaped bungalow fresh as a bee...," but in numerous episodes, his house has more than one floor, so it cannot be considered a bungalow.
- When SpongeBob spilled mustard on Jack M. Crazyfish's shirt, the mustard was still there. After they were playing rock-paper-scissors, the mustard is gone.
- In the Welsh dub, Luke Brookshier, Tom King, and Steven Banks are all listed as writers of this episode, even though none of them wrote this episode. Brookshier and King are also erroneously listed as storyboard directors.
